While a sobering 9.1% of out-of-hospital cardiac arrest victims survive to discharge overall, the real story in CPR survival rates is one of stark contrasts—where a single factor like a swift bystander response or the buzz of a public AED can mean the difference between a 2.4% chance and a survival rate soaring above 50%.
Key Takeaways
